WANs Explained

This is also known as a Wide Area Network. It’s used to connect devices that are far from another. It’s quite common for a WAN set up to be far more complex than a LAN. Essentially, you start with a LAN and then use the WAN to connect multiple LAN networks to one another. Ultimately, this means that offices can be connected and this typically occurs through public networks.

A LAN network will also typically experience less congestion whereas a WAN will tend to suffer from more. Again, this is just due to the nature of the different setups in place here.

In our changing digital landscape, cybersecurity has become paramount importance of 2019.

Cost. Typically, you will find that the LAN network is cheaper to both set up and maintain. This is once again due to the low geographical area of the system. You also don’t need to worry about leasing telecommunication lines. In contrast, with a WAN network telecommunication line leases are needed, driving up the cost. For set up, costs can be cut down by using cheap software such as a VPN but this will never be as effective as a full physical set up.

This should help you understand whether or not you need a WAN or LAN network in your business. Generally speaking, small companies will operate on a LAN system whereas larger businesses and corporations will require both. Advanced networks that use LANs and WANs, as well as subnetworks, can be incredibly complex because they all need to operate independently and as one unified system. As such, it is crucial that the right set up is utilized from day one.
